| 中文摘要: |
| 南非某低品位铂钯尾矿，其铂品位为1.1 g/t，钯品位为0.5 g/t，Cr2O3品位17.96%。采用“强磁选预富集-细磨浮选高效富集”工艺流程进行处理，以SH作抑制剂、硫酸铜作活化剂，丁黄药+SAC作铂钯捕收剂，全流程实验获得铂品位65.9 g/t，钯品位24.0 g/t，铂回收率60.93%，钯回收率48.72%，铂+钯品位89.9 g/t的铂钯精矿，同时获得Cr2O3品位39.19%，回收率70.19%的铬精矿。实现了铂钯尾矿中铂钯的有效回收，并综合回收了铬。 |
| 英文摘要: |
| A low-grade platinum palladium tailing from south Africa consists of 1.1 g/t of Pt, 0.5 g/t of Pd and 17.96% of Cr2O3. Adopting the process of “pre-enrichment by strong magnetic separation - efficient enrichment by fine grinding flotation” and using SH as the inhibitor, copper sulfate as an activator, SAC + butyl xanthate as a high-efficiency platinum palladium collector, the obtained platinum-palladium concentrate has 65.9 g/t of Pt, 24.0 g/t of Pd, and the recovery rates of Pt and Pd are 60.93% and 48.72%, respectively. The Cr2O3 grade in the chromite concentrate is 39.19%, and its recovery rate is 70.19%. The comprehensive recovery goal of platinum, palladium and chromite in platinum palladium tailings is achieved. |
